BEST SHOW OF COMMITMENT

Justin Timberlake, 23, has only one "Senorita" in his life, and that's Cameron Diaz, 31. The pop star sued News of the World on July 27 over the British tabloid's story claiming that model Lucy Clarkson spent two "sizzling nights" with him. Diaz and Timberlake, who teamed up for charity in Miami last weekend, denied the report. Said Diaz: "I trust Justin. This woman just wants her moment in the spotlight."
